AUGUSTUS OLIVER BRUMMEL, OF MEMPHIS, TENNESSEE.

Letters Patent No. 95,878, dated October 19, 1869.

IMPROVEMENT IN DRIVEN-WELI POINTS.

The Schedule referred to in these VLettera Patent and making 'paxt of the same.

To all whom it may concern:

Be it known that l, AUGUSTUS Omvnn BRUMMEL,

of Memphis, Vin the county of Shelby, and State of Tennessee, have invented a Point and Lower Section in Driving-Well; andI do hereby declare that the following is a full and exact description thereof, refer# ence being had vto the accompanying drawing, and to the letters of reference marked thereon.

Figure 1 is a sectional view, displaying itsconstruction.

C, the lower Section of point. D, inner pipe. li, upper section of point. a aa. a, air-passages in B and C. b b, groove in section B.

c, holes in the outer pipe A.

d, male screw, to attach section of pipes in driving.

c, holes in the inner pipe D.

f j, pinsrto retain in position inner and outer pipes A D. g g, slots through which the pins ff pass, controlling pipes A-D, -closing the holes c e, o1' opening them, at pleasure. p

C and B, point made of steel, one-third larger than the pipe of well.

A D, the pipe perforated.

The nature of myiuvention consists in so constructing the point in two parts, the lower section of point G being attached to the inner pipe D, and the section of point B heilig loose, revolving 011 point C, it being placed around the shoulder to which tached to section of `point C. l

The object in constructing the point in two parts, is to be able to create an air-passage to the point of the p'oint, if it become necessary to remove the pipe from the ground after driving, admittingair below, doing away with the vacuum that otherwise would be created below the point, the air passing first through tubes a a in section of point B, thence through groove b b, thence through tubes ae in lower section of point O, thus furnishing air below point O, preventing suction, the securing oi'tou'ter and inner pipes A and D with the slots g g and screws ff, and the placing of slots g reversely, giving it (A and D) nearly an up-anddown motion, and while the pipe is being driven, the holes e e and the exposing'of innerpipe are closed,

preventing the sand entering the pipe, and when it is desired to ascertain the presence of water, it matters not how far the pipe may be raised.

The section Al) can only open a given distance, bringing theholes c ein the outer and inner pipes A D, and exposing the inner pipe D adesired distance.

This lower section is attached to pipes, and driven the same as other driving-wells.

The point itself is one-third larger' at its belly than the pipes, making a larger hole than the pipe itself.

To enable others skilled in the art to make and use this, my invention, I will proceed to describe its construction and operation.

I make this point conical, in two pieces, (o nfthird larger than the pipcs,) to admit of constructing orifces or air-passages a a a a. and grooves b b, that when it becomes necessary to remove the pipe from the well, all suction is done away with; and another reason in it being constructed in two parts is, when it is driven, if the point comes in Acontact with any hard substance, it hasavrotary` motion every time it is driven, thus being able to free itself from such ob struction, the`pins and slots that allow the pipes B C to open a given distance, and allow them to free themselves of sand, by the sand passingout directly above the point.- rlhe point is made of steel.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The point O B, made in two sections, with the airpassages a a a a, in combination with b b, as described above, for the purpose there stated and described.

'2. The point C in combination with the pipes A D, constructed as above described, and for the purpose therein contained and stated.
